从C++调用C#

namespace CSharpLibrary
{
    public class MyClass
    {
        public static int Add(int a, int b)
        {
            return a + b;
        }
    }
}

#include<iostream>
#using "path/to/your/CSharpLibrary.dll" // 替换为你的C#类库DLL文件的路径

using namespace System;
using namespace CSharpLibrary;

int main()
{
    int a = 5;
    int b = 7;
    int result = MyClass::Add(a, b);
    std::cout << "Result: "<< result<< std::endl;
    return 0;
}

Result: 12
